My invention relates to an improvement in sash-fasteners, the objectbeing to produce a simple, durable, convenient, and effective device.

WVith these ends in View my invention consists in a sash-fastener havingcertain details of construction and combinations of parts, as will behereinafter described, and pointed out in the claims.

The base-plate A of the upper sash is provided with an upright post B,which is embraced by the free ends of the two arms of a yoke-shapedlever C, the said ends of the arms being pivotally secured to the postby a pin D. The outer end of the said lever is constructed withalocking-edge C and is slotted, as at C to receive a pivotalfinger-piece E, having an inwardly-projecting finger E at its upper endand an outwardly-projecting finger E at its lower end. The saidfingerpiece may, however, have other forms than that shown, if desired.It may, for instance,

to have the yoke-shaped lever drawn over it, I

as clearly shown in Figs. 2 and 5 of the drawings. A horizontal chamberG, extending through the lower portion of the said upright, receives theshank H of a locking-dog, which is provided at its outer end with anotch H, adapting the dog to engage with the lockingedge C of the saidlever. The said end of the dog is provided with a curved finger 11 forwhich a recess F is formed in the curved face of the upright. Thiscurved finger is provided for engagement by the inwardlyprojectingfinger E of the operating-piece E, whereby the locking-dogis retired toclear its notch H from the locking-edge O of the lever. The said dog isnormally pushed outward by means of an upright flat sheet-1netal springI, entered at its lower end into a transverse notch 1, formed in theupper edge of the extreme inner end of the shank H of the dog. Thisspring is located in a vertical groove J, formed in the inner face ofthe chambered upright and secured in place by providing its upper endwith two narrow lateral extensions 1 I ,which areinsertedinto slits J J,offsetting from the upper end of the said groove J. Under thisconstruction the spring is simply and firmly secured in place withoutperforating it to receive a rivet, whereby its usefulness is greatlyprolonged. hen the said dog is retired, its inner end and also a portionof the said spring enter the vertical groove B, formed in the inner faceof the post. The said chambered upright is pro vided at the upperextremity of its curved lifting face with a shoulder K, which cooperateswith the locking-edge C of the yokeshaped lever, as shown by Fig. 7 ofthe draw ings, in sustaining the upper sash in a Very slightly loweredposition for ventilation.

Under the described construction the yoke shaped lever co-operates withthe lifting-face of the chambered upright in lifting the upper sash intoits lockin g position and drawing the two sashes together in case theyare not rightly adjusted before the lever is drawn over the upright. henthe leveris in its locked position, it is impossible to tamper with thedevice from the outside of the window, as a knife or any thin edgeinserted between the sashes cannot be manipulated so as to lift thelever. The several parts of the device, as will be observed, are ofstrong and simple construction, and will not therefore break or get outof order.

I have already stated that the operatingpi'ece, instead of beingpivotally mounted in the outer end of the lever, may be mounted so as toreciprocate therein. Under this construction the shape of the outer endof the locking-dog will be somewhat changed. I would therefore have itunderstood that I do not limit myself to the exact construction hereinshown and described, but hold irf-yself at liberty to make such changesand alterations therein as fairly fall within the spirit and scope of myinvention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Ina sash-fastener, the combination,with a base-plate provided with apost, of a yokeshaped lever pivoted thereto, an operatingpiece mountedin the outer end of the said lever, a base-plate provided with achambered upright having its outer edge curved to form a lifting-face toco-operate with the lifting-leverwhich fits over'the upright, and aspring actuated dog mounted horizontally in the said upright to engagewith the outer end of the lever and lock the same in its closedposition, substantially as set forth.

2. In a sash-fastener, the combination, with a base-plate provided witha post, of a yokeshaped lever pivoted thereto, an operatingpiecemountedin the outer end of the said lever which has a locking-edge, abase-plate provided with a chambered upright having its outer edgecurved to form a lifting-face and constructed with a shoulder located atthe upper extremity thereof, and a springactuated locking-dog mountedhorizontally in the said upright to engage with the lockingedge of thelever, substantially as set forth,

and whereby the upper sash may be sus-- tained in a slightly-depressedposition for ventilation by engaging the said edge of the lever with theshoulder of the upright.

In a sash-fastener, the combination, with a base-plate provided with apost, of a yokeshaped lever pivoted thereto, an operatingpiece mountedin the outer end of the said lever, a base-plate provided with achambered upright having its outer edge curved to form a lifting-facewhich cooperates with the lever which fits over the said upright, alocking-dog mounted horizontally in the said upright and the said leverand provided with an inwardlyprojecting finger, a base-plate providedwith a chambered upright having its outer edge curved to form alifting-face which is recessed, and a spring-actuated dog mountedhorizontally in the said upright to engage with the outer end of theyoke and lock the same in its closed position and provided at its outerend with a curved finger fitting into the recess in the curved face ofthe upright and adapted to be engaged by the inwardlyprojecting fingeron the operating-piece, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
